Tutankhamun's tomb, discovered by archaeologists in the Valley of the Kings on Nov. 4, 1922, was found loaded with treasures. Some of those artifacts, like his death mask, are widely known. But others, such as a mannequin that may have helped the boy king choose what to wear, are less famous but offer insight into King Tut's life. Here are 30 fascinating treasures from Tutankhamun's tomb and what they reveal about the iconic ancient Egyptian pharaoh 100 years after the discovery of his remains.

Flushed toilets emit aerosols that spread pathogens contained in feces, but little is known about the spatiotemporal evolution of these plumes or the velocity fields that transport them. Using laser light to illuminate ejected aerosols we quantify the kinematics of plumes emanating from a commercial flushometer-type toilet, and use the motion of aerosol particles to compute velocity fields of the associated flow. The toilet flush produces a strong chaotic jet with velocities exceeding 2 m/s; this jet transports aerosols to heights reaching 1.5 m within 8 seconds of initiating a flush. Quantifying toilet plumes and associated flow velocities provides a foundation for future design strategies to mitigate plume formation or to disinfect pathogens within it.

Photographing the Northern Lights is a thrilling experience.
There aren’t many events as moving as seeing the aurora borealis dance and illuminate the night sky with mesmerizing movements and vibrant colors.
To help you find inspiration for planning and executing your images, in this new edition of the Northern Lights Photographer of the Year, we present the 25 best aurora images captured around the world.
Buckle up because this trip is going to take you from the remote boreal forests of the Arctic to the far landscapes of the Southern Hemisphere, passing by spectacular lakes, mountains, and beaches along the way…always with the Northern Lights dancing in the sky.

The EctoLife Artificial Womb Facility envisages a controversial new way to be pregnant, with the baby growing in an idealized, but completely inhuman environment: transparent "growth pods" arranged by their hundreds in human baby farming operations.
To be clear from the outset: this is just a concept at this stage, the brainchild of Berlin-based "producer, filmmaker and science communicator" Hashem Al-Ghaili. There are no immediate plans to build an EctoLife facility, this is merely a piece of science fiction Al-Ghaili has extrapolated from the current state of fertility research.

Canadian researchers have discovered two minerals never before seen on Earth, in a sample of 15-tonne meteorite found in Somalia, the ninth-largest meteorite ever found. 🪨✨
The new minerals have been named elaliite and elkinstantonite.

LAST March, brain-computing interface expert Tom Oxley sat down to dinner with Amazon.com founder Jeff Bezos to talk about Oxley’s nascent company, Synchron That meal in Ojai, Calif, ended with something better than dessert: Bezos told Oxley that he wanted to invest in the business.
Synchron said on Thursday (Dec 15) it completed a US$75 million funding round, part of it from Bezos Expeditions.
The financing was led by ARCH Venture Partners, and includes a cheque from Gates Frontier, the venture investment arm of Microsoft co-founder Bill Gates, and others. Existing investors also participated, including Khosla Ventures – whose founder, Vinod Khosla, introduced Oxley to Gates.
Brain-computer interfaces, known as BCIs, can interpret and stimulate parts of the brain and are seen as a possible treatment for brain injuries. New investors approached Synchron “through the lens of making an impact in neurology in an area of need,” Oxley said in an interview. They “saw BCI as a future therapeutic.” About 100 million people globally have upper limb impairment, he said, and could benefit from the technology.

Like another interesting advance in material science we looked at back in 2016, the team’s creation uses the unique properties of a protein as a starting point. Where that previous example took advantage of a protein’s counter-intuitive compression capabilities, the University of Kent team has drilled into the natural shock-absorbing abilities of a protein called talin, and used it to create a family of hydrogel materials called TSAMs (Talin Shock Absorbing Materials).

Westminster City Council are fighting back against people who urinate in public by treating walls with a pee paint that give perpetrators a nasty surprise if they attempt to relieve themselves on it.
The paint creates a water-repellent layer so that urine and other liquid bounce back onto the perpetrator doing the peeing, leaving them soaked.

We know that we do have some subscribers from Philippines and from US.
Guys, just don't forget this...
Filipino Zoo Girl was displayed at the Coney Island Zoo in 1904. She was a zoo attraction among the monkeys and lizards to show off the new US possessions in the Philippines. She was bound by ropes. Visitors threw her peanuts.

Glass frog turning transparent as it sleeps
The researchers found that the frogs maintained roughly the same level of transparency while awake, calling, exercising, and under anesthetic.
However, when they were sleeping, the frogs were between 34 and 61 percent more transparent than during waking activity.
Optical spectroscopy on 13 frogs confirmed that a decrease in circulating red blood cells is the reason for the increased transparency on their undersides. Red blood circulation decreased by up to 89 percent, and the red blood cell signal was concentrated in the liver.

World's largest aircraft engine is fully operational and ready to test
Rolls-Royce says it's finished building the first demonstrator for its massive UltraFan engine, which will eventually hit the skies in airliners to be developed in the 2030s. Testing begins soon, with expectations of a 25% leap in efficiency.

This is the underside of an elephant's foot. The sole of an elephant is full of cracks. Like the fingerprint of people or the stripes of a zebra, those cracks are unique to each elephant. That means, if the tracking conditions are good, that you can identify an individual elephant just by its footprint. The amount of cracks also increases by age, so you can also get an indication of an elephant's age, just from its footprints.
Elephants communicate over long distances with infra sounds, inaudible to the human ear. In the feet of elephants, there are a lot of sensitive nerves that pick up these low frequencies from the ground. So, you could say that elephants can listen with their feet.

Secret ingredient found to help ancient Roman concrete self-heal
Concrete is the most commonly used building material in the world, but it’s not impervious to damage. Weather and stress can lead to tiny cracks, which can grow into much larger cracks that eventually threaten the integrity of the entire structure. That can require expensive maintenance or replacement to prevent catastrophic failure.
In contrast, ancient Roman structures have stood the test of time for more than two millennia. To find out how, scientists have long examined samples of the material under microscopes to study the composition and uncover the ingredients that bestow such strength.
